Dumbbell Incline Hammer Curl

Anton YefanovUpdated September 6, 2026

The dumbbell incline hammer curl is a hammer curl performed seated on an inclined bench, with the arms hanging back behind the body. The neutral grip biases the brachialis and forearm, while the inclined position pre-stretches the working muscles before each rep. The result is a curl that builds visible upper-arm thickness from a stretched start.

How to do the Dumbbell Incline Hammer Curl

Set a bench to about a 60 degree incline and sit back with a dumbbell hanging from each hand.
Let the arms fully extend straight down, palms facing each other, with the shoulder blades pinned to the bench.
Keep the elbows pinned at your sides and resist any urge to swing them forward as you curl.
Curl both dumbbells up by bending only at the elbow, palms staying in the neutral hammer position.
Stop the curl just before the elbows travel forward, squeezing hard for a brief pause at the top.
Lower the dumbbells under control over 2 to 3 seconds back to the fully stretched start position.

Muscles worked

Primary:: Biceps

Why train it

Builds upper-arm thickness through the brachialis under deep stretch.
Develops forearm size and grip strength through the neutral grip.
Removes momentum cheating through the seated, anchored position.

Common mistakes

Letting the elbows drift forward at the top, which removes the brachialis stretch the lift is designed for.
Rolling the shoulders forward off the bench, swapping arm work for front-shoulder strain.
Rushing the lower portion and dropping out of the stretched bottom where the growth happens.
Loading too heavy, which forces a swinging cheat rep and ruins the isolation.
